ABSTRACT:
In accordance with this invention, a DRAM with a staggered bitline sense amplifier configuration utilizes an I/O data path scheme which minimizes the time delay through the I/O data path. The DRAM includes a first and a second memory arrays wherein a first external sense amplifier receives on an input terminal a signal corresponding to the state of a memory cell selected from the first memory array via a first column decoding circuit. A second external sense amplifier receives on an input terminal a signal corresponding to the state of a memory cell selected form the second memory array via a second column decoding circuit. Each of the two external sense amplifiers has an output terminal which are shorted together. A tristate signal feeding another input terminal of each of the two external sense amplifiers is used to eliminate data contention on the shorted output terminals.
